Qhia peb cov qib siab polyacrylamide (PAM) flocculants, ib qho kev daws teeb meem tsim los txhim kho cov txheej txheem kho dej thoob plaws kev lag luam. Kev tsom mus rau kev ua tau zoo thiab kev ua tau zoo, peb cov khoom PAM tau tsim los ua kom tau raws li cov kev xav tau tshwj xeeb ntawm koj cov kev xav tau ua haujlwm thaum ua kom pom kev ua haujlwm zoo.
Thaum xaiv flocculant, muaj ntau yam tseem ceeb los xav txog. Peb cov qauv PAM muaj peev xwm flocculation zoo heev, thiab lawv qhov hnyav molecular tuaj yeem tsim kho kom muaj zog ntawm flocs, ua kom muaj kev ua tau zoo nyob rau hauv ntau yam xwm txheej. Peb nkag siab tias tus nqi ntawm flocculant plays lub luag haujlwm tseem ceeb hauv nws cov txiaj ntsig, uas yog vim li cas peb cov khoom tau raug kuaj xyuas nruj kom ntseeg tau tias cov txiaj ntsig zoo.
Peb cov PAM flocculants tsis yog tsuas yog ua tau zoo, tab sis kuj hloov tau zoo heev. Lawv nyob twj ywm zoo thoob plaws ntau yam ntawm pH thiab qhov kub thiab txias, ua rau lawv zoo tagnrho rau kev hloov pauv ib puag ncig. Cov qauv molecular tshwj xeeb ntawm peb cov PAMs ua kom zoo solubility thiab kev ua haujlwm siab, ua rau cov flocs loj uas txhawb cov sedimentation sai. Qhov tseeb, peb cov PAMs muaj 2-3 lub sij hawm muaj peev xwm qhia tau ntau dua li lwm cov dej-soluble polymers.
Tsis tas li ntawd, peb lub tuam txhab cov khoom siv polyacrylamide yog tsim los nrog kev saib xyuas tag nrho ntawm cov neeg siv kev paub. Lawv cov corrosiveness tsawg thiab cov txheej txheem siv yooj yim heev txo cov kev siv zog thaum ntxiv thiab txhim kho kev ua haujlwm. Tom qab kev kho mob, cov khoom raug tshem tawm hauv dej tau zoo flocculated thiab meej, thiab tuaj yeem txuas seamlessly txuas nrog ion txauv kev kho mob los npaj cov dej ntshiab uas ua tau raws li lub teb chaws tus qauv.
Xaiv peb cov polyacrylamide flocculants los muab kev txhim khu kev qha, ua tau zoo thiab ib puag ncig zoo rau koj cov teeb meem kho dej. Kev paub qhov txawv ntawm peb cov khoom PAM tuaj yeem nqa thiab txhim kho koj cov txheej txheem dej huv niaj hnub no!
